Title: Fluid suspension spring and damper for vehicle suspension system
Inventor: DAVIS LEO W
IPC: B60G13/00
Filed: 1987-12-10
Granted: 1992-06-09
Abstract: ABSTRACT OF THE DISCLOSURE A  vehicle  with  a  suspension  system  having  a compressible liquid confined in a cylinder and compressed to a  predetermined  static  pressure.    A  damping  piston  is disposed on a double ended rod where the rods have different cross sectional areas to provide a differential area which is acted on by the liquid to spring support the weight of the vehicle.  The end of the larger rod is connected to the vehicle chassis and bearings in each end of the cylinder transfer high bending moments due to wheel loads.  Friction is reduced by eliminating contact between the large diameter piston and cylinder, and limiting frictional contact to the relatively small diameter of the bearings and seals.  Total fluid volume is increased to provide a lower spring rate by a fluid chamber within the rod, and apparatus is provided to control ride height by changes in liquid pressure and/or volume which also changes spring rate.   Apparatus is also provided  for adjusting damping and thus  effective spring rate from the fixed end of the rod.

Title: High frequency ventilation method
Inventor: REESE DAVID M
IPC: A61H31/00
Filed: 1988-03-17
Granted: 1991-06-04
Abstract: ABSTRACT OF THE DISCLOSURE    A method of ventilating an air breathing animal at a high frequency.  A flow of gas is supplied to the first side of a piston mounted within a housing while the flow of gas out of the housing is restricted to elevate the pressure on the first side of the piston. A flow of gas is also supplied to the second side of the piston, which is connected to an air breathing animal, while the piston is alternately moved back and forth within the housing at a selected frequency, amplitude and period, thereby alternately forcing gas into and drawing gas out of the animal.          The flow of gas out of the animal is also restricted to elevate the pressure on the second side of the piston.  The flow of gas to the first side of the piston both cools the piston and housing and helps to equalize the pressures on both sides of the piston, helping to insure accurate conversion of the mechanical movement of the piston into a pressure wave in the gas on the second side of the piston.

Abstract: IN THE CANADIAN    PATENT & TRADEMARK OFFICE            PATENT APPLICATION entitled:  Novel palladium-based alloys containing tin and their use in the glass industry, especially for protecting components against corrosion by molten glass in the names of: Jean-Paul GUERLET                  Jean-Pierre HILGER             Assignee:  Société Anonyme styled:  COMPTOIR LYON-ALEMAND LOUYOT                  ABSTRACT OF THE DISCLOSURE The invention relates to a novel palladium-based alloy.        This palladium-based alloy comprises tin in an amount, preferably of 5 to 20% by weight, which is sufficient to impart an acceptable resistance to corrosion by molten glass, preferably being essentially equivalent to that of platinum-rhodium 10% alloys.        An alloy of this type can be used in the glass industry for making components which come into contact with molten glass, which preferably essentially contains no oxides less stable than tin oxide, such as lead oxide, because it has an excellent resistance to corrosion by molten glass and is much less expensive than the platinum-rhodium 10% alloy normally used. Moreover, by the addition of at least one element selected from platinum (0-50% by weight), rhodium (O-20% by weight), iridium (0-20% by weight) and ruthenium 0-20% by weight), the mechanical strength at high tem-perature, especially the creep strength, is significantly improved.

Abstract: -??-Abstract of the Disclosure Method and System For Determining Surface Profile Information A system determines the surface profile of an object.  Systems of this kind are used in industrial robots, such as automatic welders.  The severe operating environment requires a vision system with noise immunity along with accuracy.  A beam splitter enables the use of discrete optical detectors which eliminate many problems inherent with previously used detectors, such as diode arrays and TV cameras. Additionally, an automatic gain control alters the intensity of a generated optical beam in response to the reflectivity of the surface.  These features increase the accuracy and noise immunity of an optical vision system for use in severe industrial applications.

IPC: G06F11/00
Filed: 1989-03-23
Granted: 1993-04-20
Abstract: A B S T R A C T     Arrangement for Error Recovery in a Self-Guarding Data Processing System In self-guarding data processing systems most of the error handling activities have to be implemented without any program support from a dedicated subsystem which is secured against the error problems which it has to handle. The self-guarding data processing system must be reset and restarted to handle the error procedures by itself. This means that the error status manifested in many check latches has to survive the reset and restart activities and that it has to be accessible by instructions within the processor in error. Check indicator latches are provided which are set by the error signals and which are read by the error handling program routines for further evaluation. They can only be reset by the error handling program routines.

Title: Tracking device for optical memory card
Inventor: HORIE KIYOSHI
IPC: G11B7/0033
Filed: 1989-04-03
Granted: 1993-07-20
Abstract: ABSTRACT:    A tracking device performs tracking correction by moving a mobile objective lens of an optical system in -the transverse direction of tracks on an optical memory card in accordance with the tracking error of the optical system relative to the optical memory card.  The tracking device includes comparison means for determining whether or not tracking error information is within a predetermined standard range and for generating a direction signal that represents the direction for correction, correcting signal generating means for generating a correcting signal when the result of the determination conducted by the comparison means is negative, and retaining portion moving means for moving a retaining portion of the objective lens in the direction indicated by the direction signal in response to the correcting signal delivered from the generating means.          When it has been determined by the comparison means that the deviation occurring during tracking is within the predetermined standard range, tracking is performed by moving the mobile objective lens in the transverse direction of the tracks.  When the deviation in the tracking is outside the standard range, the retaining portion of the mobile objective lens is also moved in the transverse direction of the tracks to perform tracking correction.  In consequence, the range in which tracking correction can be performed is enlarged, and an accuracy with which data is written on and read from the optical memory can be thereby improved.
